Shane, it looks like you have some really good knives there. Some might be worth keeping as heirlooms or as users, but if you don't know much about knives, if you aren't a knife person, you are probably best off selling the high-end models. Each of them can be worth a couple hundred dollars or more. That adds up in a hurry.
The best way to start is by inventorying what you've got. Group them by manufacturer. Make a line entry like you did for the knives above, with whatever information is obvious, and if at all possible, include a picture of each.
At that point, you can see the patterns of information emerging, and searching ebay for similar models and the prices they go for will be much easier.
There really is no book value on knives, especially production knives. Probable values can shift throughout the year, as people sell to cover taxes or vacation or holiday expenses. Some currently issued knives may become discontinued, which may raise their value.
So even if we give you a good ballpark value, it may not be what the knife brings on a sale. And part of that depends on where you sell them. And that will determine how much information you need to provide the potential buyer.
